Edaravone Dexborneol for Blood-Brain Barrier Repair in Acute Anterior Circulation Stroke
A Multicenter Randomized Controlled Trial Study of the Effect of Edaravone and Dexcamphan on the Repair of Blood-brain Barrier Injury in Acute Infarction of Anterior Circulation
This multicenter randomized controlled trial evaluates the effect of edaravone dexborneol on blood-brain barrier repair in patients with acute anterior circulation large artery atherosclerotic ischemic stroke within 48 hours of onset.
Patients are randomized 1:1 to receive either edaravone dexborneol (30mg/7.5mg BID IV) or edaravone (30mg BID IV) for 9±2 days, in addition to standard stroke treatment. The primary outcome is the change in blood-brain barrier permeability (Ktrans) measured by DCE-MRI. Secondary outcomes include neurological function scores, serum biomarkers, and safety events.
